Kedu ihe dị iche n'etiti xanthan gum na HEC?

Xanthan chịngọm na Hydroxyethyl cellulose (HEC) bụ hydrocolloids na-ejikarị eme ihe na ụlọ ọrụ dị iche iche, gụnyere nri, ọgwụ, ihe ịchọ mma, na ngwaahịa nlekọta onwe onye. N'agbanyeghị ịkekọrịta ụfọdụ myirịta na akụrụngwa na ngwa ha, enwere ọdịiche dị iche n'etiti abụọ ahụ.

Nhazi na nhazi:

Xanthan chịngọm:
Xanthan chịngọmbụ polysaccharide sitere na gbaa ụka nke carbohydrates site na nje Xanthomonas campestris. Ọ nwere glucose, mannose, na glucuronic acid, haziri n'ụdị nwere nnukwu alaka. Ọkpụkpụ xanthan chịngọm nwere nkeji glucose na mannose ugboro ugboro, yana eriri akụkụ nke glucuronic acid na otu acetyl.

HEC (Hydroxyethyl cellulose):
HECbụ ihe sitere na cellulose, nke bụ polymer na-emekarị na mgbidi cell nke osisi. Na mmepụta nke HEC, ethylene oxide na-emeghachi omume na cellulose iji webata ìgwè hydroxyethyl na ọkpụkpụ azụ cellulose. Nke a mgbanwe enhances mmiri solubility na rheological Njirimara nke cellulose.

Njirimara:

Xanthan chịngọm:
Viscosity: Xanthan chịngọm na-enye nnukwu viscosity na ngwọta mmiri ọbụlagodi na obere mkpokọta, na-eme ka ọ bụrụ ihe na-eme ka ọ dị mma.
Àgwà ịkpa agwa: Ngwọta nwere xanthan gum na-egosipụta omume na-akpachapụ anya, nke pụtara na ha na-adị ntakịrị viscous n'okpuru nrụgide siri ike ma nwetaghachi viscosity ha mgbe ewepụrụ nrụgide ahụ.
Nkwụsi ike: Xanthan gum na-enye nkwụsi ike na emulsions na nkwusioru, na-egbochi nkewa nke oge.
Ndakọrịta: Ọ dakọtara na ọkwa pH dịgasị iche iche ma nwee ike iguzogide okpomọkụ dị elu na-enweghị atụfu ihe ndị na-emepụta ihe.

HEC:
Viscosity: HEC na-arụkwa ọrụ dị ka thickener na-egosipụta elu viscosity na aqueous ngwọta.
Ndị na-abụghị ionic: N'adịghị ka xanthan gum, HEC abụghị ionic, nke na-eme ka ọ ghara inwe mmetụta maka mgbanwe na pH na ike ionic.
Ịmepụta ihe nkiri: HEC na-emepụta ihe nkiri transperent mgbe a mịrị amị, na-eme ka ọ baa uru na ngwa ndị dị ka mkpuchi na adhesives.
Nkwenye nnu: HEC na-ejigide viscosity ya n'ihu nnu, nke nwere ike ịba uru na ụfọdụ usoro.

Xanthan chịngọm:
Ụlọ ọrụ nri: A na-ejikarị Xanthan chịngọm eme ihe dị ka ihe nkwụsi ike, onye na-agba ume, na onye na-ahụ maka gelling n'ọtụtụ ngwaahịa nri, gụnyere sauces, uwe, ihe ebe a na-eme achịcha, na ngwaahịa mmiri ara ehi.
Ihe ịchọ mma: A na-eji ya eme ihe ịchọ mma dị ka ude, lotions, na ntacha eze iji nye viscosity na nkwụsi ike.
Mmanụ na Gas: Xanthan chịngọm na-arụ ọrụ na-egwupụta mmiri na ụlọ ọrụ mmanụ na gas iji chịkwaa viscosity na kwụsịtụ ihe siri ike.

HEC:
Agba na mkpuchi: A na-eji HEC eme ihe nke ukwuu na agba mmiri, mkpuchi, na nrapado iji chịkwaa viscosity, meziwanye ihe ndị na-asọpụta, na ịkwalite mmepụta ihe nkiri.
Ngwaahịa nlekọta onwe onye: Ọ bụ ihe a na-ahụkarị na ngwaahịa nlekọta onwe onye dị ka shampoos, conditioners, na creams n'ihi na ọ na-eme ka ọ sie ike ma na-eme ka ọ kwụsie ike.
Pharmaceuticals: A na-eji HEC mee ihe dị ka onye na-ekekọta ihe na mbadamba mbadamba yana dị ka ihe na-ekpo ọkụ na ọgwụ mmiri mmiri.

Ndịiche:
Isi mmalite: Xanthan chịngọm na-emepụta site na gbaa ụka nje, ebe HEC sitere na cellulose site na mgbanwe kemịkalụ.
Character Ionic: Xanthan gum bụ anionic, ebe HEC abụghị ionic.
Mmetụta nnu: Xanthan chịngọm na-enwe mmetụta maka oke nnu dị elu, ebe HEC na-ejigide viscosity ya n'ihu nnu.
Nhazi ihe nkiri: HEC na-emepụta ihe nkiri transperent mgbe akpọnwụwo, nke nwere ike ịba uru na mkpuchi, ebe xanthan gum adịghị egosipụta ihe onwunwe a.

Omume viscosity: Ọ bụ ezie na xanthan gum na HEC na-enye nnukwu viscosity, ha na-egosipụta àgwà dị iche iche nke rheological. Ngwọta Xanthan chịngọm na-egosi omume na-akpụ akpụ, ebe ngwọta HEC na-egosipụtakarị omume Newtonian ma ọ bụ ihe dị nro dị nro.
Ngwa: Ọ bụ ezie na enwere ụfọdụ ndakọrịta na ngwa ha, a na-ejikarị xanthan chịngọm eme ihe na ụlọ ọrụ nri yana dị ka ihe mgbakwunye mmiri na-egwupụta ihe, ebe HEC na-ahụta ọtụtụ ojiji na agba, mkpuchi, na ngwaahịa nlekọta onwe onye.

mgbe xanthan chịngọm na HEC na-ekerịta ụfọdụ myirịta dị ka hydrocolloids eji eme ihe na-eme ka usoro mmiri sie ike ma na-eme ka mmiri sie ike, ha dị iche na isi iyi ha, àgwà ionic, mmetụta nnu, ihe na-emepụta ihe nkiri, na ngwa.
